Unrecoverable fault

Traindune

Everytime I try to play GTA IV I get this error that says Unrecoverable fault. Please restart game. Why am I getting this? I only have 1 mod and its Native Trainer. sometimes I can play for 15 min and it will happen but most of the time I can play only 5 min and it happens. Here is my PC specs below. Also, I will remove the mod and get a fresh install to see if I get it without the mod.
